Abstract: Utilization of quantum dots in displays and the location of the quantum dot sheet within the stackup of the backlight can lead to issues such as non-uniform light mixing, non-uniform brightness, and off-axis changes in color. The mismatch between the isotropic nature of light emitted from the quantum dots and the light emitted directly from the light source can be alleviated by utilization of diffusers and prism sheets. The diffusers and prism sheets can be further utilized to change the angle of light such that it is directed upwards towards the top of the display for improved uniformity in brightness and enhanced performance. Placement of the diffuser sheets, prism sheets, and changes in the design of the components, such as the light guide path, can alleviate the issues by properly mixing the colors together in order to achieve a uniform distribution of colors in the display.
